now I'm PISSED

I got the first response gold digital pregnancy test with two tests in one box. AND BOTH TESTS DO NOT WORK!!!😡😡😡 the directions say a blinking clock is supposed to appear and nothing ever appeared! $30 DOWN THE TOILET 😡😡😡😡 I feel like screaming right now because I also had rude customer service when buying it because my bf bought the wrong one so I went back to exchange it for this another one and because his cards chip wasn't working or the machine was not reading it they wouldn't give it to us and they had such AWFUL ATTITUDES the cashier AND the manager had horrible horrible attitudes mind you me and my boyfriend are extremely polite and friendly. I don't get it. I feel like the world is just against me right now. Ok rant over. I think I'll go tomorrow and see if I can get my money back
